Title: Blood serum applicator for electrophoresis samples - having two thin plates held apart by spacer with crossbars held in place by stays these being offset for greater strength and rigidity
Inventor: FURUHASHI HIROSHI
IPC: B01L99/00
Filed: 1979-07-18
Abstract: Applicator comprises (a) a thin plate which supports a cross bar at its end by two support stays, one of which is at the edge and the other off centre; (b) a second thin plate is similar to the first but is a mirror image. These two are combined with a spacer between them so that the stays are offset. The gap between the two cross-members will then hold a small sample of blood serum which can be applied to a cellulose acetate film to form a consistent, uniform film across it. This is then subjected to electro-phoresis for monitoring its contents. Used in blood analysis. Existing applicators have the problem that one of the cross bars is only supported by one stay and is easily damaged. This gives non-uniform application. The claimed applicator is of a more rigid construction.

Title: Underground coal gasification - applies radially travelling gasification front
Inventor: WENZEL WERNER PROF DR ING
IPC: E21B43/247
Filed: 1980-02-29
Abstract: An underground in situ gasification system for coal seams is based on a central extraction borehole which is surrounded by a ring of injection boreholes for the gasifying agent. The gasification channel extends from a first injection borehole to the central and from an adjoining to the first injection borehole. When this dogleg channel approaches the radial direction the third borehole is brought into similar action. The gasification channel thus travels radially completely around the extraction borehole. It is thus better adapted to the fact that more intensive reactions occur near the injection than near the extraction borehole.
